Pull Request Overview
This PR improves the performance of pre-commit hooks by implementing selective file processing. The key optimization is to run checks only on changed files and their associated packages rather than the entire codebase.
- Added file-based filtering for markdown code block linting via a new
--no-globflag - Created a new script to run pyright checks only on packages with changed files
- Refactored pre-commit task configuration to pass changed files to checking tools

| File | Description |
|---|---|
| python/run_tasks_in_changed_packages.py | New script that identifies which packages have changed files and runs tasks only in those packages |
| python/pyproject.toml | Updated pre-commit tasks to accept file arguments and pass them to the new selective checking scripts; added missing coverage entries and removed unused doc tasks |
| python/check_md_code_blocks.py | Added --no-glob flag to treat file arguments as literal paths instead of glob patterns |
| python/.pre-commit-config.yaml | Removed pass_filenames: false to enable passing changed files to the check command |
| python/packages/chatkit/pyproject.toml | Fixed typo: changed extend to extends for pyright configuration |
| python/packages/anthropic/tests/test_anthropic_client.py | Added env_file_path parameter to improve test isolation |

Motivation and Context
Our pre-commits were getting very slow, and this was mostly due to check md code blocks.
Description
Added file handling based on the pre-commit for check_md_code_block formatting, they now only run on changed
.mdfiles.Also ensured pyright on pre-commit checks which packages need to be checked, also speeding things up.
Cleanup
